Commercial solar installation: your questions

Which buildings suit commercial solar?

Warehouses, offices and retail buildings with roof space are the usual fit. Where the roof does not suit, ground-mounted systems are an option.

Do you handle the grid connection?

Yes. We handle the paperwork and coordination with the network operator.

Do you check the roof first?

Yes. The site audit covers the roof, the structure, the electrical supply and how you use energy.

Can solar be part of a wider fit-out?

Yes. We plan it with the rest of the works, as part of a warehouse fit-out or an office fit-out.

What size of projects do you take on?

We take on projects from £100,000 to £10M+.

What have you built?

Commercial projects such as the Banbury warehouse, Portsoken House, its reception and Beaumont House.
